Sealed unit headlamp replacement kit to 7" H4 on ebay

that would be our old friend robert hack. do a search on him and you'll see not to go there.

 

How is it that he can say "H4" when they are not H4? I guess one does have to be careful.

 

DO NOT deal with that guy if you value your money. I made the mistake of dealing with him and I strongly suggest that no-one else makes the same mistake.
If you want a cheap h4 conversion there is one that is a direct replacement for the 7" sealed beams and is sold by JC Whitney. I posted it a couple of months ago. You could probably find it easily with a search.

 

I think they are H4, just not the 8" H4 that everyone wants (so you'll still have the chrome trim ring). H5s also come in 7" and 8" IIRC.

Vertex Auto has 7" H4s for $55 (I think for the pair, but check to be sure).

 

Here is a copy of my original post on the subject. For some reason I couldn't copy and past a link because my browser always shows forums.rennlist.com/ no matter what thread I'm in. Wierd. Anyway, here it is.

I Wrote: I was surprised to find that JC Whitney has H4 halogens that are designed to be direct replacements for sealed beams in the following wattages. 130/90, 100/80, 60/55 . The prices range from 37.99 each to 32.99 each. H4's are supposed to be illegal in the US for on road usage because of their higher output. But I'm sure if you used a little lower wattage than the max you could probably get away without any problems. JC Whitney stock numbers are wh139301 for the 130/90's change the last digit to a 2 or 3 for the other wattages.

By the way, I have no affiliation with JC Whitney. I just saw this and thought someone could save a little moolah.

Jim Bailey Wrote : These are the 7 inch replacement for the 7 inch seal beam units used on USA 78-86 car and NOT the big flat 8 Inch 928 headlights used on Euro cars or the similar looking 87-95 model 8 inch H-5. With the 130/90 bulbs these little lights are quite bright compared to the anemic US mandated sealed beam lights. It is a cheap upgrade if you do not mind having that chromed plastic trim ring around the headlight. It also give you greater choices of bulbs since any H-4 bulb will fit the lens reflector assembly.

I hope this helps guys.

 

Are they H4? Because H4 is a rating, and the beam is focused in a top-cut pattern ...

 

These are drop in replacements for the sealed beam unit. I have this in my other 928s too. Mine are original Bosch units, 7" dia and the bulbs have the same end as the sealed unit so no modifications to the wiring harnes are needed. The Bosch units guarantee a 100% inprovement in night time visibility and I can say this is true. Huge improvement for a fraction of the cost to convert to the 8" H4s.

I'm sure you can buy them form somewhere else.

 

Guys,
H4 really refers to the bulb type right? - otherwise known as a 9003 bulb.

For a Porsche 928 'Hella H4' or 'Bosch H4' 8" lamps are special lamps with lenses designed for H4 buibs and have a particular sharp cutoff European projection pattern - but in general a lamp that has H4 bulbs could be anything - and certainly could be DOT compliant depending on its structure. 928 specific H4's are not DOT compliant but actually don't really have much higher total light output from the bulbs than US DOT spec H5's do - its mostly about the beam projection pattern.

Nope, "H4" is on the lens and it means that the top of the light emitted is flat ...

 

Heinrich,

H4 is indeed on the lamp lens - no debate. It is indeed a Bosch H4 lamp. I think its clear what this means in the context of a 928 and yes I do have 2 of them and they are great....

But I think that just means its a specific design of H4 lamp designed for H4 bulbs and maybe specifc to a 928....do a search on google for "H4 Bulb"... tons of them and for lamps of different types even for motorcycles...

My point - "H4" Is a more generic term than its usage in context for a 928 suggests....

Alan

 

Alan you are correct. For us 928'ers though it is important to know that if someone sells you H4 lights and they have H4 bulbs in them but are not Porsche 928 H4 lights including the lenses, you've been had

 

Heinrich,
Yes I agree - Just telling someone you have H4's for a 928 and not delivering Hella or Bosch versions is a essentially still a scam.... Unless you are totally up front about what the content is and how it differs from "The Real Thing"

Caveat Emptor.... as they used to say.....

Alan

 

H4 is both a bulb type (comes in different wattages) and a lens/reflector optimized for that bulb. The lenses come in different styles - there are generic round (at least 7 and 8", probably others) and rectangular H4s lenses and also H4 lenses that are custom designed for a particular car model (like on the 911).

 

If you do not go with original spec H4 lights, both Hella and Cibie offer an equivalent drop-in replacement for any standard sealed-beam headlight. In 7", the Cibie Z-beams are the schiznit IMHO, though apparently NLA in the US. Hellas well set you back about a C-note and can be had at most performance shops. I have a set of these on the early Z-car I'm trying to sell, and they have the exact same beam pattern as my 8" H4's on the shark. They are not quite as effective as the 8" units, I believe because of the smaller reflector. But it's the same pattern. And IMHO they are exactly equivalent to the 7" Bosch H4's that I took off of my shark. IMHO you're taking your chances with the "lowest-bidding supplier" versions at JCW.
